HackerRank(sWap cASE)

You are given a string and your task is to swap cases. In other words, convert all lowercase letters to uppercase letters and vice versa.

For Example:

Www.HackerRank.com → wWW.hACKERrANK.COM
Pythonist 2 → pYTHONIST 2  
# Solution 1:--
def swap_case(s):
    result = ""
    for letter in s:
        if letter == letter.upper()
            result += letter.lower()
        else:
            result += letter.upper()
    return result
## Solution 2:--
def swap_case(s):   
    return s.swapcase()
